GEORGE DAVIS, OF RICHMOND, VIRGINIA.

FOOT-POWER.

SPECIFICATION forming part of Letters Patent No. 288,778, dated November20, 1883. Application filed September 14, 1883. (No model.)

To all whom it may concern:

Be it known that I, GEORGE DAVIS, of Richmond,Henrico county, Virginia,haveinvented a new and Improved Foot-Power, of which the following is afull, clear, and exact description.

This invention is for an improved device for turning the driving-wheelof a foot-power for a lathe or any other machine adapted to run byfoot-power; and it consists of the hereinafter described and claimedcombination and arrangement of parts.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my improved foot-power, and Fig. 2 is afront elevation of the same. Fig. 3 is aside elevation, showing amodified form of the stirrup-lever and of its fulcrumsupport.

A is the stirrup-lever, connected with the driving-wheel B by thecrankpin b of its crank 22, which enters a socket provided therefor inthe lever A. It has at its lower endthe stirrup a, and at its upper enda slot, a, adapted to receive the pin E, on which lever A has averticalmotion. Stirrup a is adapted to receive the foot of the operator.

C is a hanger attached to the under side of I the bench or table D,which supports the lathe or other machine. Hanger 0 has a slot, 0,adapted for the reception of bolt E, and in which bolt E may be adjustedup or down. Bolt E has a collar, 6, fitting against the side of hangerO, and is secured thereto by a washer, 0, and nut 6 and is adapted tofit into the slot a of lever Aas a fulcrum-rest therefor and to allowthe lever Ato move vertically thereon.

Driving-wheel B is of any ordinary construction, and adapted for eithera flat or a round belt. It is supported on its axle in bearings by thehanger H, which is attached to the under side of bench D, or it may behung in a support resting on the floor.

The operation is as follows: The several parts being adjusted as abovedescribed, the operator places his foot in the stirrup, and by downwardpressure, pushing, pulling, or by an upward pressure of the foot on thestirrup, the wheel is started and caused to revolve.

The advantages of my invention are,that at whatever point thedriving-wheel may stop it may be readily started by either pressingupon,

lifting, pushing, or pulling on the stirrup with the foot, whereas inusing the ordinary construction the wheel is liable to stop at aposition where it cannot be started by the stirruprod. My improvementcan be operated with greater ease, as the pushing motion is more naturaland morepowerfulthan adirect downward pressure of the foot of theoperator, because he does not stand directly over the place where thepressure is to be applied. v

In the modification of my invention shown in Fig. 3, the support 0 restsupon and is secured to the floor. 'Ihe fulcrum-rest a for lever A is inthe end of a lever, F, which has a vertical rocking motion about thepivot f in the support 0-, and thus allows the stirruplever A to have avertical motion, as in the arrangement shown in Figs. 1 and 2. Lever Fhas a weight, f, at its extremity f to counterbalance the weight of thelever A.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The slotted hanger O, in combination with thestirrup lever A, substantially as herein shown and described.

2. In a foot-power, the combination, with the crank 11 of abalance-wheel and the slotted hanger O, of the slotted stirruplever Aand the adjustable fulcrum -pin E, substantially as described and setforth.

GEORGE DAVIS.
